Thanks Sal for your comments on the article TI: Sensortag CC2650 . This is for you and those who are playing with TI SensorTag!
I've updated the repository of the Texas Instrument (TI) SensorTag CC2650. The repository can be found here . As you may know TI doesn't update the repository anymore. The original last open source repository of the application can be found here .
I've wrote an article last year as I migrated and updated the repository:
Today, I've updated the repository to support Android 8.1 (>6.0). The main modification was that Android >6.0 needs location permission for BLE to work. It was first reported as a bug but Google closed the report with status: Won't Fix (Intended Behavior):
To access the hardware identifiers of nearby external devices via Bluetooth and Wi-Fi scans,
your app must now have the ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION permissions
I've created a new repository for the Texas Instrument SensorTag CC2650. I updated the open source TI repository, which can be found here.
Due to licensing restrictions (I do not know which ones) Texas Instruments was no longer able to keep the open source code in sync with the SensorTag application in Google Play. That means, the new version in Google Play has more features than this one. But this is open source, and can be modified and extended! I am planning to collect the sensor data and publish on a Google Cloud IoT PubSub topic.
I had some humidity problems in the basement and I thought I can buy a dehumidifier. I bought the this one on ebay Dehumidifier 500ml. I knew they are not good enough, but I wanted to try.
This type of dehumidifier uses a peltier element to cool an alumium disipator (peltier cool side), which condenses the humidity. The condensed humidity drips into a water tank until it is full. Then, a switch is triggered and the system stops. The peltier hot side has a bigger disipator and together with a fan disipate the generated heat.
Connect the OmniVision ov7670 -old but everywhere- (version with FIFO AL422B) to the LaunchPad Tiva™ C Series EK-TM4C1294XL and take photos over serial interface, or use the http webserver to get a (slow) video streaming.
